The mol-ecule of the title Schiff base compound, C17H16N4O4, has crystallographic twofold rotation symmetry. The nitro and CH=N - C substituents are coplanar with the benzene ring in each half of the mol-ecule. These two planar units are parallel, but extend in opposite directions from the central methyl-ene bridge, so there is no intra-molecular π-stacking. Instead, mol-ecules pack with approximately parallel inter-leaved benzene rings providing inter-molecular π-stacking, the centroid-to-centroid separation being 3.7196 (18) Å. © International Union of Crystallography 2007.
